GLASS SHOW-CASE.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed March 25.1907. Serial No. 364,218.

To all whom 'it may concern: y

Be it known that I, ALrHoNs OLBERG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Glass Show- Gases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- \pertains to make and use the same.

My invention relates to show cases which are made up chiefly of glass plates, and is directed to improved means for rigidly tying together the several plates or sections.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In glass show cases, at least the top, sides and front thereof are made up of glass plates, and it is desirable that these be secured together and to the bottom of the case Without requiring the glass plates to be perforated and by the use of the least possible amount of metal or other opaque material which is used for the purpose of making such connections. My invention meets these requirements and is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the sev eral views.

Referring to the drawings, Figures 1, 2 and 3 are views respectively, in plan, front elevation and side elevation, 'showing a show case embodying my invention. Fig. 4 is a fragmentary view in plan, showing one of the front corner portions of the case. Fig. 5 is a bottom plan view of the parts shown in Fig. 4. Fig. Gis a vertical section taken on the line .t6 x6 of Fig. 4. Fig. 7 is a vertical section taken on the line x7 x7 of Fig. 4. Fig. 8 is a detail in horizontal section, taken approximately on the line fc3 x8 of Fig. 3, some parts being removed and some being broken away. Fig. 9 is a fragmentary detail in vertical section, taken on the line x9 ai of Fig. 2. Fig. l0 is a fragmentary detail in section, taken on the line :uw :1510 of Fig. 3; and Fig. 11 is a fragmentary detail in section, taken on the line ai x11 of Fig. l.

The base plate 1 of the case may be constructed of metal, wood, or any other suitable material, but for the purposes of this case we will assume the saine to be constructed of metal. Channel-shaped rear corner posts 2 are rigidly secined at their lower ends to the base 1, and at their upper ends they are tied together by a transverse channel bar 3 rigidly secured thereto, preferably by solder. Said corner posts 2 and channel bar 3 have their inner flanges bent laterally to form door stops.

The numeral 4 indicates the glass side plates, the numeral 5 the glass top plate and the numeral G the glass front plate of the case. The said side plates 4, at their vertical rear edges, are set into channels of the corner posts 2, and their lower edges are set into grooves in the base plate l.y The top plate 5, at its rear edge, is set into the channel of the transverse tie bar 3. The lower edge of the front plate 6 is set into a groove formed in the front portion of the base plate l. At the upper front corners of the case, the abutting edges of the side plates 4, top plate 5 and front plate 6, are, respectively, seated in grooves or seats 4, 5a and 6a of metallic corner brackets 7. These metallic corner brackets 7 are tied together by a thin metallic strip 8, and they are'also tied to the respective corner posts 2 and to the bottom plate 1, respectively, by thin metallic strips 9 and 10. These metallic strips are of ribbon-like form and preferably are faced with strips or ribbons of felt, indicated by the numeral 1l. The felt faced metallic strips 8-11 are interposed between the upper edge of the front plate 6 and the overlying under surface of the top plate 5, and the ends of said strip 8 are soldered or otherwise rigidly secured to the inner portions of the corner brackets 7. The felt faced metallic strips 9-11 are interposed between the upper edges of the side plates 4 and the overlying under surface of the top plate 5, and the ends of said strip 9 are secured by solder or other means to the interior of the alined corner brackets 7 and upper ends of the alined corner posts 2. The upright felt faced metallic strips lO-ll are interposed between the vertical front edges of the side plates 4 and the adjacent inner surfaces of the iront plate G, and the upper ends of the said strips l0 are secured by solder or other suitable means to the interiors of the vertically alined corner brackets 7 and to the alined front corners of the base plate 1. The felt or pliable facings ll are preferably stuck to the cooperating metallic strips and to the engaging portions of the glass plates by a suitable adhesive material.

The opening at the rear of the case formed between the rear edge of the bottom plate l, the rear corner posts 2 and thetransverse tie bar 3, is adapted to be closed by a door, preferably in the form of a glass plate l2 connected to one of the said corner posts by a hinge 13 and engageable with the door stops on said corner posts 2 and tie bar 3, and having at its inner edge a finger-piece 14.

ln a showcase constructed as described, the metallic tie strips or binders 8, 9 and 10 are nearly or entirely invisible, while the pliable faeings ll when made of a greenish color or of approximately the color of one of the glass plates when viewed edgewise, willalso be nearly invisible. The showcase, therefore, has the appearance of being made almost entirely of glass and at the same time the metallic tie strips 8, 9 and l0 rigidly tie the corner brackets 7 with respect to each other and with respect to the bottom plate 1 and to the upper ends of the corner posts 2, in such manner that they can not move relatively thereto and, hence, serve to positively secure the glass sides, top and front plates of the case together and against separation. It is, of course, important to note that this is also accomplished Without requiring the said glass plates to be perforated. The perforation of these glass plates is objectionable, first, because it weakens the plates, and second, because it is an expensive operation in that the perforation thereof is a slow job and further because of the large percentage of breakage incident to the operation.

The showcase, so-called, may be constructed in various sizes and dimensions. A showcase of the kind described has been made and found to be very strong and highly elicient for the purposes had in View.

What I claim is:

In a showcase, the combination with a base, of channel-shaped rear corner post rising from said base and having their inner flanges bent laterally to form door stops, a channel-shaped tie bar connecting, the upper ends of said corner posts and having its inner flange bent laterally to forni a door stop, a door hinged to one of said corner posts and engageable with said door stops, glass side plates seated at their lower edges on said base and at their rear vertical edges in said channel corner posts, a glass front plate seated on said base, a glass top plateseated at its rear edge in said channel tie bar, corner brackets in which the adjacent corners of said side, front and top plates are seated, a metallic strip connecting -said corner brackets and interposed between the said top plate and upper' edge of said front plate, metallic strips connecting said corner brackets to the upper ends of said corner posts and interposed between said top plate and the upper edges of said side plates, and metallic strips connecting said corner brackets to said base and interposed between said front plate and the front edges of said side plates, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ALPHONS OLBERG.
